How to fix your Samsung Galaxy S7 Edge that won’t turn on & won’t boot up after an update [Troubleshooting Guide]

There is a big difference between a #Samsung Galaxy S7 Edge (#S7Edge) that won’t turn on and won’t boot up and you will learn about it in this troubleshooting guide. A unit that doesn’t turn on may be a sign of a serious firmware issue or hardware problem. When you say “won’t turn on” it means that the phone doesn’t power up when you hit the Power key. More often than not, they won’t also charge when plugged in.

On the other hand, if the phone doesn’t boot up, it means there’s power but the problem is that it cannot successfully load all necessary services and apps that’s why it gets stuck while booting up. It might be a problem with the firmware or can also be a sign of a serious hardware issue which may involve the battery.

I have addressed these issues in this post so read on to understand more about them and learn how to fix each problem just in case you’ll encounter one of them in the future. While we suggest safe troubleshooting procedures, things might happen unexpectedly due to human error. So proceed at your own risk.

Fix your Galaxy S7 Edge that doesn’t turn on after an update

Problem: Hi. I hope you can help me because I really to have my phone working again. First off, my phone is a Galaxy S7 Edge that I bought brand new about 5 months ago. It has worked without issues since then until a couple of days ago when an update was automatically downloaded and probably installed. The phone turned off on its own and the screen remained black since then. No matter what I do, it just wouldn’t respond nor turn on. I tried charging it but it wouldn’t as well. I’m really frustrated right now and I badly need your help guys. I hope you can find a solution for this. Thank you and I will be waiting for your response. — Josie

Troubleshooting: Hello Josie! Let’s go straight ahead with your device’s problem. Issues like this is very common, it happened when the downloaded files are corrupted or damaged during the download process and they cause problems to a device, in this case, a Galaxy S7 Edge. We have a lot of readers who have encountered similar problem and we already addressed some of them. Hopefully, we can help you resolve the problem by following some of the recommended troubleshooting steps below:

Step 1: Forced Restart your Galaxy S7 Edge

Sometimes simply rebooting the system is the easiest way to resolve the issue. There are cases that after an update the device need to restart to complete the update process, a Galaxy S7 Edge has a unique feature that will allow the device to reboot if there is a software problem detected. However, it is not a guarantee that this feature will work every time so you have to do it manually.

To do the forced restart, press and hold the VolumeDown button and then press and hold the Power key. Keep both keys held down for 10 seconds until the device boots up. Assuming the phone has enough battery to power it up, then it should start up normally, otherwise, move on to the next step.

NOTE: This procedure will rule out the possibility that the problem was caused by a frozen device due to system crash.

Step 2: Try charging your device

If the issue is not resolve after performing the first step, then try charging your phone and see if the LED indicator is blinking and leave it for several minutes. This will allow the device to store energy to power up the device; problems turning the device on are sometimes caused by uncharged battery. Also, see if the device will display the default charging logo when turned off. If so, then your device is responding and turn it back on if you think the stored energy is enough to power the device. However, in case it won’t turn on then try the other recommended steps below.

Now, if it happened that the culprit of the problem is a third party app, then try booting your device to Safe Mode. In this mode it will temporarily disable all third party app installed in the device, running only the default app by the manufacturer. While on this mode, you can simply uninstall the suspected app or the most recent installed app before the problem occur. Identifying the app is sometimes difficult especially if you can’t remember what app is causing problem. Anyhow, we highly recommend to try it, below are the steps how to run your device in Safe Mode:

Press and hold the Power key.

As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.

Continue holding the Volume Down button until the device finishes rebooting.

You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

After performing the steps and it doesn’t work or did not resolve the issue, then the next step below.

Step 4: Try starting it into the Recovery Mode

Since the problem happened after the software update, we can’t set aside the possibilities of hardware problems. There are cases that hardware problem is causing the device to become unresponsive, no matter how much effort you put into it, the device just won’t turn on. So, we recommend to run the device into Recovery Mode just to see if it can because if so, then the hardware is fine, you may then proceed with the wiping of the cache partition or a master reset for that matter. Here are the steps on how to start up your phone into the Recovery Mode:

Turn off your Samsung Galaxy S7 Edge.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

If it can’t boot up into this mode, then proceed to the next step.

Step 5: Have a technician take a look at it

After performing all the recommended troubleshooting steps above and the issue still occurs, then a trip to the nearest Samsung service center is your last resort to have this problem fix. Odds are that your device experiences a software problem during the update process and causes the device to become unresponsive and possibly damaged it, or it might be a more serious hardware issue. So, at this point, you need help from someone who can perform further tests on your phone to determine what the issue really is.

Troubleshoot your Galaxy S7 Edge that won’t boot up successfully

Problem: There was like as update three days ago and I downloaded it not knowing it would cause a problem on my phone. At first, the update seemed fine but then the device rebooted and got stuck on the logo. I left it like that for a couple of hours as I had to run errands. When I came home, the phone was still showing the logo but then I left it alone for another hour but no improvement so I decided to turn the phone off and started it back up. It went passed the logo but got stuck on the black screen. Now, I can’t use it anymore since it can’t reach the home screen. How can you fix a problem like this? — Matt

Troubleshooting: Regarding your issue, there are a lot of factors to consider to determine why it is happening in the first place, what caused it and how to fix it.

Perhaps, due to the recent firmware update, the system and app caches might have been corrupted and that might have triggered the problem that left your device stuck on the logo. The best thing that you should do is to perform a software troubleshooting to determine if the issue is caused by corrupted caches, downloaded apps or if it has something to do with the phone’s hardware. To begin with the software troubleshooting, follow the procedures below.

Step 1: Try booting up your Galaxy S7 Edge in Safe Mode

There’s an instance wherein a third-party app may become incompatible to the new system that was installed on your device and that’s one of the key reasons why your phone cannot boot up properly. In this procedure, all third-party apps will be temporarily disabled and only the pre-installed apps will run. So, if the issue is not happening while in this mode there’s a chance that there’s a third-party app that’s causing the issue. To boot your device in Safe mode, follow the steps above. If the phone cannot successfully boot up in this mode, then try the next step.

Step 2: Try wiping the cache partition of your device

There is a possibility that the system and app caches of your phone got corrupted due to the firmware update. Perhaps, the old caches are not compatible with the newly installed firmware so everytime the phone uses them, this problem is triggered. So, the next thing you have to do is try to delete the system cache and all cached files. Follow these steps to do so:

Turn off your Samsung Galaxy S7 Edge.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’

Once highlighted, you may press the Power key to select it.

Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.

Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.

The phone will now reboot longer than usual.

Step 3: Perform Master Reset on your phone

After performing the procedures above and the issue is still happening on your phone, then doing a master reset is your last resort. This procedure will bring back your device to its defaults settings and all stored files will be deleted. So, if possible before doing this procedure, try to backup all your files because all of them will be deleted.

Turn off your Samsung Galaxy S7 Edge.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’

Once highlighted, you may press the Power key to select it.

Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.

Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

The phone will now reboot longer than usual.

Step 4: Have a technician re-install the firmware

After doing the master reset on your Galaxy S7 Edge and the issue still remains, then the next thing that you need to do is to re-install the firmware of your phone. In this case, we recommend that you should bring your phone to the store where you purchased it and let the technician flash the firmware. You may do it yourself but there’s always a chance you’ll trip the Knox counter and void the warranty, so have an authorized tech do it for you to be safe.

BONUS PROBLEM: Galaxy S7 Edge get stuck on the logo sometimes

Problem: I have scoured your website but I haven’t found anything that addresses my issue specifically. I own the S7 Edge but recently I noticed it slowed down and heats up unlike it was heating up before. I mean, it heats up so bad now that it is almost uncomfortable to hold it when it does. Yesterday it restarted on its own a couple of times and every single time it couldn’t go straight to the screen where there are apps instead it’s stuck on the logo. I just want to be able to use my phone like before. Help me fix these issues please. Thanks!

Troubleshooting: You are actually experiencing a general performance issue, which is often characterized by poor performance speed, slow response, app crashes and force closes, random reboots or shutdowns, and getting stuck on the logo during boot up. The good thing about it is that your phone can still boot up so we can troubleshoot it. That being said, here’s what you must do:

Step 1: Restart your device into Safe Mode

This is will immediately give you an idea whether the problem is caused by one of the third-party apps or not. Applications may crash sometimes and instead of closing, they may affect the firmware and cause conflicts between processes. As a result, the firmware itself crashes and during boot up, necessary services may not be loaded due to conflicts. Booting in safe mode will temporarily disable all third-party apps and services. If one of them caused the problem, then the phone should be able to boot up normally in this mode.

If the phone has successfully booted up in this state, continue using it without your third-party apps to see if the problem still occurs and if so, then go after the firmware immediately.

Step 2: Factory Reset your Galaxy S7 Edge

We tried booting your phone in safe mode to see if the problem still occurs and it does, so the problem could be in one of the pre-installed apps or the firmware itself. It will take you forever to find the app that’s causing the problem and when you do, there’s nothing you can do because you cannot uninstall it unless the phone is rooted. So, at this point, the most logical thing to do is to reset your phone. So, backup all your data and files and then follow these steps to do the Factory Reset:

From the Home screen, tap the Apps icon.

Find and tap Settings and then touch Backup and reset.

Tap Factory data reset and touch Reset device.

If you have screen lock feature turned on, enter your password or PIN.

Touch Continue.

Tap Delete all to confirm your action.

I hope this helps.
